Review on 🎧 Koss Porta Pro On-Ear Headphones with Microphone and Remote Control, In-Line Mic, Touch Control, Collapsible Design, 3.5mm Plug, Black/Silver by Jacob Brooks

I hope Koss keeps making these as they're still a great choice for in-ear headphones. Sounds great without isolating you from the outside world. Mine have been abused in the time I've had them (about 6 months I think) and they wear just as well. At first I was concerned because the folding mechanism looks a bit spindle-shaped. The built-in microphone and controls work great too. There are no complaints. PS This rating tool also asked me to review the battery life. To my knowledge they don't have a battery so I'm not sure what they mean. Like most headphones, they are powered by a mini-plug.
